AUTOMATICALLY REFBIGERATING ItE.t'JEPi'IACLIl Application led May 31, 1928. Serial No. 281,759;

This invention relates to refrigeration, and its principal object is to provide a receptacle which will automatically and directly cool or refrigerate the liquid or other substance 5' which is to be consumed or utilized at the reduced temperature. I

In carrying out the invention resort is had to the well known principle which involves a liquefying gas and chamber therefor, a gas absorbent and chamber therefor which is in communication with said former chamber, provision for removable heating means for the absorbent, and provision for cooling the liquefying gas. In the embodiment of this invention the receptacle for the substance which is actually to be consumed or utilized i is directly enveloped by the liquefying chamber of the process While the latter chamber is in turn directly enveloped bythe gas ab,- sorbent chamber of the process.

Other objects and advantages will hereinafter appear.

The accompanying drawing shows an ele- Vation, partly in cross-section and partly in full, of the receptacle constituting the invention.

s here shown,- the receptacle 1 is formed as an ordinary pitcher or jug having the j in the chamber 12, producing in turn the consequent rapid and eiiicient cooling or refrigso' usual mouth 2, sto per 3, spout 4, and hanj die 5. The inner c amber 6 of the receptacle holds the utilizable liquid 7 to be refrigerato d or cooled, such as beverages, etc., and the wall 8 of this chamber is enveloped by a heatinsulated Wall 9, which is in turn enveloped by the exterior wall 10 of the receptacle. The

disposition of the `walls 9, 10 is such that they form spaces, receptacles, or chambers 11, 12, the latter of which envelops the wall 8 or chamber 6 and the former of which en- 0 velops the insulation wall 9, or may be said to envelop the chamber 12. As here'shown, the wall 9 consists of adouble layer of plates 13 between which is filled any suitable heat msulation material 14, such as asbestos. In the chamber or receptacle 11 is located a gas absorbent 15, such as water or, as here shown, charcoal, or any other suitable substance may be utilized which underordinary temperatures will eiciently absorb ammonia or any other hqueymg gas that may be suitable for this typeiof refrigeration process. The

chambers or receptacles 11, 12 are in communication with each other through a passageway l'gf'lhe receptacle or jug 1 is seated in aheating stand 17, comprising a platform 18, Isupporting legs 19, and a double wall 2Q, which surrounds the lower portion of the exterior wall` 10`of the jug and carries an electric heater unit 21, the conducting cable 22 of which may be plugged into any w convenientffeed socket, not shown.

i When it isV desired to refrigerate or cool the contents 7 ofv the jug'l, water is first poured into a chamber Gand the current is turned on to the heaterl 2 1, and the heat, penetrating the 65 wall 10 to the absorbent 15, then frees the aml monia, which enters through passageway 16 into the chamber or receptacle.12 and is, after reaching acertain pressure, therein liquefied, by virtue of this chamber beingy cooled by o the said water retained in the chamber 6,` Thereuponffthecurrent may be shut off, the jug removedfrom the stand 17, the water poured out,j;and the utilizable contents 7 inserted into tlie chamber 6, to thereby quickly remove theheat from the absorbent 15, which sharply lowers the gas pressure and causes the rapid evaporation of the liquefied ammonia eration of the utilizable liquid contents 7. Incidentally the ammonia is reabsorbed by the charcoal 15, and the normal condition of the entire receptacle 1 is'then restored, ready for a repetition of the same process.

The jug 1 may be adapted for use in connec' tion with a gas heater, instead of the electric heater here shown. In case aqueous ammonia or similar liquid gas-absorbent should be utilized, the passageway 16 may be pro- 90 vided with a check-valve 23, hinged at 24, which permits the free passage ofthe gases between the chambers 11, 12, but operates to preclude the exit' of any of the aqueous ammonia from its chamber 11, when the jug is inverted for pouring out'the water or the contents, or for cleaning purposes. Any of the Well known cut-oil ,devices and safety valves may be installed on this receptacle for shutting off at a predetermined time the curoping said wa l, and said last two receptacles being in communication with each other.

It will be also evidentth'at after the contents of this jug have been refrigerated they will continuev y to be retained at a low temperature'for a long time, due tothe clamber 6 e the insulation wall 9 and the intervening chambers 11, 12, which also conduce to the insulation of the contents.A l A Variations may be resorted to within the scope of the invention, and portions ofthe im rovements may be yused lwithout others. aving thus-described ourv invention, we claim 1.
